[Piglit] [PATCH 2/4] util: Add common framework for command-line invoked subtests

From: Ian Romanick <ian.d.romanick at intel.com>
There are two parts to this.
First, command line options of the form "-subtest foo" have their
argument (the "foo" part) stored in a list in the
piglit_gl_test_config. Tests can use this functionality without having
to use any of the other parts. This allows every piglit test to have
the same syntax for specifying which subtests to run.
Second, tests can create a list of piglit_gl_subtest structures. Each
structure describes a single subtest: the name (as it will apear in the
log), the command-line name (as supplied to -subtest), and the function
that implements the test. Helper function use this table and the list
of tests specified by -subtest options to run a group of tests.
The next patch shows an example of using this functionality.
